lujvo x1 (letteral: la'e zo BY/word-bu) is a hyphen/joining letter(al) in language x2 with function in/context of use/with rules for use/with properties x3, joining prefixed unit/lexeme/morpheme/string x4 (quote) to postfixed unit/lexeme/morpheme/string x5 (quote) in construct (full word) x6 (quote) x1 joins words/morphemes/particles into a single cohesive, grammatical unit. x4 and x5 may be improper quotes. In English, "-" is such a hyphen letteral; in Lojban, ybu, ry, ny, and ly are such hyphen letterals (arguably, as is y'y). The fact that the letteral is used to join words is implicit and this function therefore need not be specified in x3 in most cases.

experimental cmavo mekso operator: finite result set derived from/on set A with/due to operator/function B under ordering of application C Equivalent to: lo'i li zy du ca'e li pe'o se'au mau'au B zai'ai vei ma'o xy boi ny ve'o boi tau sy boi C ku poi ke'a cmaci xanri zi'e poi ke'a mleca li ci'i zo'u tau sy klesi A. Acts on an operator/function (b) and produces all finite results of that operator being used on any allowable number of elements of the set A without repetition within any given application. The result must be defined (and finite, obviously). Application of the operator on nothing (the elements of the empty set) is generically allowed and follows convention (for example, an empty sum may evaluate to 0). Differs from kei'ai. Use mau'au and zai'ai for quoting B. C will be specified explicitly (possibly elsewhere) and/or via zoi'ai.
